Topic tags/keywords: question tip maple tablesaw milling traditional

I’m just getting into building my first pieces of furniture and learning joinery. I got a DeWalt contractor table saw, and I built my youngest son a toddler bed out of hard maple with some mortise and tenon joints. I didn’t like some of the things about the saw, so I upgraded to a metal top saw in the Delta 36-725.

When I went to cut some more legs from my big piece of maple (I think it is 12/4 Hard Maple based on research), the saw kept shutting down and really struggling, especially on rip cuts, but even on cross cuts on a piece the size of a table leg. It will trip my power surge protector unless I go very slowly. In any case, I’m able to cut through it, but extremely slowly and getting burn on the rip cuts. In some rip cuts, the maple starts to pinch down on the saw (riving knife helps with that).

Is this too big or too hard of lumber for this saw? (I didn’t even know it was 12/4 or what that meant until I started googling) Or do I need a new blade? Or is this just how it goes with basic homeowner saws on really thick, hard wood? The blade seems aligned very well.

Any advice appreciated! I love this maple lumber that I found, but wondering if there is a better way to get the pieces out of it that I need.

Even 3hp saws will bog down on 12/4 hard
woods. Perhaps your saw won’t do it in one
pass. Try cutting at 1” depth, then re-cutting
at 2” and so forth.

Try getting a good thin kerf 24 teeth blade. Freud Diablo is excellent

If you are using the stock blade, go buy a better blade. Freud Diablo or Irwin Marples. Also that saw needs a full 20A circuit, check that your surge protector is rated for 20A and not 15A. Don’t use 14 or 16 gauge extension cords. I have that saw and use a Marples blade cutting 3” oak with no problem.

From Delta… A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20-amp time lag fuse.

From Why Me …. Dump the surge power protector.

I’ll just reiterate all the great advice above. Along with getting a decent 24T thin kerf blade, double check the alignment, and check the supply circuit.

Sounds like a classic symptom of insufficient juice… and having a ‘surge protector’ doesn’t really give me the warm fuzzies either :)

Ok wow thanks for all that knowledge. I hadn’t considered that I would have to change electrical wiring in my garage. And I will definitely check out a new blade, another thing I didn’t anticipate being a thing, ha ha. But dang they are $$. My wife really has no clue what I’ve gotten into. But she wants custom furniture, so no complaints by me!

Yep. Need better blades and for specific purposes will stock that thick. Among other things.

Do you have any 20A outlets in your garage? If so, use them and ditch the surge protector. Either way, if your home has been built in the last 25 years, ditch the surge protector.

I was running my table saw off a 15A outlet that was also running a refrigerator, an oscillating fan (it is hot and humid here in NC), a cordless drill battery charger, and my table saw on a 100ft extension cord all plugged into a power strip (the thing I calleda surge protector because it has a switch that kept tripping). I’m sure you are all laughing, but I’ve never given electrical capacity much thought.

Much to consider tomorrow when I check my circuit board to see if there is a second circuit in the garage. Ordering a 24 tooth Freud Diablo now (if I found the right thing, it is only $26 on Amazon).

Keep doing stuff like that and your motor will get toasty and let the magic smoke out – and they ain’t cheap to replace.

I think I am just living out the axiom in your signature, though I’m not very young. I will be careful to not burn it out. So what do people do? Add dedicated circuits in their garage for each large tool?

A suitable blade will start at around $30, so considering the significance of it’s role, that’s really a fairly small percentage of the cost of the saw. Irwin Marples (not Marathon or Classic), Freud Diablo, DeWalt Precision Trim, or CMT ITK Plus all make decent examples of the right blade at a reasonable cost. Lowes has the Hitachi 311128 for $23 that’s a decent blade, and should also be suitable for this task. For a bit more money, the Infinity 010-124, Freud Industrustrial LU87R010, or CMT Industrial 202.024.10 are a step up.

A 100ft cord! Oh no, ditch it. I bet that cord is only 15A. You need a 20A cord and keep it to no more than 25ft.

Also a good blade is $40 and up. I suggest at least a 40 tooth blade.

- sethpackham

No need for a circuit for each tool unless you have them all running at the same time. I have a 15A circuit for lights and small things like battery chargers, a 20 A circuit I run all 110 power tools on and a 230V/30A circuit for my 230V tools.

Get your circuiting right and check the saw for proper fence alignment, along with a new blade. at 1 ½ HP, you’re pushing the saw pretty hard and even a slight bind from misaligned fence can push ir over the limit.
